Which import(s) is/are necessary? I get an class Xml not found message. I've used a different approach using the DocumentBuilder. So I get an xml-Object which is no ivy-object which is actually fine for me. Ah - just to mention - this project is in an 4.3 environment. Beside that - is the role node necessary or was this just an example?

There is no import necessary because Xml is a standard Xpert.ivy data type. The xml in xmlDocument is an expamle. Your Xml will look different of course. I have written the example code in Xpert.ivy 5. But it should also work in 4.3.
